(54) Roller bed for a conveyor belt system


(57) A bed rail assembly apparatus adapted to be inserted between idlers (127) in an existing conveyor system (100). The bed rail assembly apparatus includes a support rail (123) oriented substantially parallel to and beneath the conveyor belt (104). A first bed rail assembly on a first side of the support rail and is oriented at an angle to the horizontal surface of the conveyor belt to support a first side of conveyor belt to be inclined upwards. Small diameter, closely spaced rollers, are affixed to the inclined surface of each bed rail assembly to support the inclined side of the conveyor belt and reduce friction between the rollers and the conveyor belt (104). A second inclined bed rail assembly on a second side of the support rail (123) is inclined upwards to support a second inclined side of the conveyor belt (104). Small diameter rollers are affixed to the inclined surface of the second bed rail assembly to incline upward a second side of the conveyor belt and to reduce friction between the second inclined bed rail assembly and the conveyor belt (104).
